IMPROVEMENT lN PUMPS..

Specification forming part of Letters Patent No. 35,677, dated June 24, 136.2.

to an iron flange, and other novel features by which I make a cheap and durable anti-freer.4 ing pump.

To enable others to make and use my in- Vention, I will describe its construction and operation. l

I make the barrel and valve-seat`V in one piece, stoneware being preferred, the shape as shown at A, with a portion of the upper end of larger diameter externally, as shown at B, by which it is fastened to the flange C with four bolts and the washer D.

L is the valveseat.

The flange C is fastened tothe wood pipe E. The other end of pipe E is fastened to flange F. This is fastened to the double flange G with two bolts. Theother end of flange G is fastened to the pump H.

I is the cap of the pump. sheet metal, as shown at I).

o 0 is the iron bottom of the pump H. This I make in four parts, so that it will yield to the shrinkage of the wood H.

R is a water-chamber and float. The object of this is to draw water horizontally and keep the pipe 3 and barrel A always full of water. Motion being given to the handle, the water runs throughthe small pipe S into the chamber R, raises the iioat l, and opens the valve 2, so that the water runs into the well-pipe 3 and continues to run until the pump is at rest and the pipe E empty to the top of the small pipe 2, and the chamber R sufficiently empty to let I cover it with Y the iioat l shut the valve 2, so that the barrel A and pipe 3 are always full of water. Io prevent the iron flanges C and F from rotting the -wood pipe E, I put between the iron and wood some other metal that is less liable to rot the wood than iron, lead being preferred. This is shown at Fig. 4, pipe 3.

No. 2 shows my ventilator used when the pump stands over the water.

The iron bottom o e, No. 1,is fastened to the top of the frame 2. Said frame is fastened to the platform by the corners 4 4 4. Vhen neeessary, I line the inside of the frame 2 to keep the frost ont of the well.

No. 3 shows the plunger and valve. The feet of the cross-piece l project from it in opposite directions in line with the edge of the valve-seat 2, to which it is riveted.

3 is avalve-guide.

4 is the valve.

5 is the washer to keep the packing to the seat 2. This is fastened with the screws 6 6.

4 are frietionless joints.

2 2 2 2 are strips of rubber fastened to the shaft l. The other ends are fastened to the wood 4, at 3 3, in a recess. The projection 5 prevents a sidewise motion of the shaft l.

6 is thejoint on the end of the rod.

7 is a projection to which the strip o is fastened.y The other end is fastened to the joint 6. In this is a recess lined with leather. Into.

this recess fits a projection of the handle.

8 is a guide to prevent a sidewise motion of the handle. The parts next the handle are covered with leather. The end part of the handle is very smooth, to prevent wear of the leather.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

l. Making the barrel A, with the exterior' enlargement, B, and valve seat L in one piece, the washer D, as used in combination with the enlargment B and flange C, the float l, valve 2, water-chamber It, and small pipe S, as constructed and combined with barrel A and pipe 3, the lead lining 4, or equivalent, fastening the flange F to the wood pipe E, the combination of the flange G with the pump H, the iron bottom o o, as made and combined with the wood H, the ornamental cap I, as constructed and covered with the metal P, the,

ventilator No. 2, as constructed and combined with the pump H, the plunger No. 3, as constrncted, the feet of the cross-piece l, projecting in opposite directions in line with the valve-seat outer edge and riveting it to said seat, and the washer 5, as :fastened with the screws 6 6 to the seat 2.

2. The rubber strips 2 2 2 2, No.4, 0r equivalent, as combined with the shaft l and pump 3, joint 6, as constructed and combined with strip o and projection 7', and the guide S and its lining of leather or equivalent, all as and for the purpose described.
